Eureka altima stopped power mid vaccuming, have changed outlits

Make sure all your filters are clean,try to turn the brush roller by hand a few times if it turns real freely then the belt is broke.if it is reall hard to turn then you have something wrapped around the ends of the roller where the bearings are.your motor guard might be keeping it from running because it got too hot take the brush roller out and the belt let it cool down for 20 minutes then try it without the roller and belt.you should be able to take the ends of the roller off by just pulling out on them so you can remove what ever is in there
